Comments :
It is used in radiology to staging the tyroid cancer This is extracted from the AJCC7th edition " Imaging may be used as an important
adjunct to identify the presence of submucosal extension,
especially at the anterior commissure where lesions may spread
anteriorly along Broyle’s ligament to involve the inner cortex
of the thyroid cartilage. Imaging may also identify glottic carcinomas
that have occult transglottic or subglottic spread. The
normal paraglottic space is often diffi cult to routinely detect at
the level of the true vocal cord due to the close apposition of
the lateral thyroarytenoid muscle to the inner cortex of the
thyroid cartilage. Tumor erosion limited to the inner cortex of the thyroid cartilage indicates a T3 lesion whereas carcinomas
that erode the outer cortex of the thyroid cartilage defi ne
a T4a tumor. Stage T4 (a and b) is diffi cult to identify based on
clinical examination alone as the majority of the criteria cannot
be assessed by endoscopy and palpation."
